％、感熱素子２でプリントされた濃度が２（反射
率が10-2の時）であると、全体の濃度ＤはＤ＝
log10（１／反射率）の式より、
Ｄ＝log10｛１／（10-2×90×10-2
＋１×10×10-2）｝
＝log101／0.109＝log109.2
≒0.96
となつて、全体の濃度が半分以下になり、画質の
劣化となつていた。 However, when printing as described above, the gap g between the heat sensitive elements 2 requires at least about 15μ, so even if the heat sensitive elements 2 are made to generate heat, the temperature in the gap g does not rise, and the gap g between the heat sensitive elements 2 The color development in some areas was poor, causing deterioration in image quality. For example, the gap g is 10 with respect to the pitch P of the heat sensitive element 2.
%, and the density printed by thermal element 2 is 2 (when the reflectance is 10 -2 ), the overall density D is D=
From the formula log 10 (1/reflectance), D=log 10 {1/(10 -2 ×90×10 -2 +1×10×10 -2 )} = log 10 1/0.109=log 10 9.2 ≒0.96 As a result, the overall density was reduced to less than half, resulting in deterioration of image quality.

However, as mentioned above, when black printing is performed immediately or before or after primary color printing is completed, the platen is shifted by half a pitch and the black portion is further printed. The density of blacks increases, the contrast becomes stronger, and the image quality can be improved. And again, Figure 18, 1
9, the cam follower 58 enters the cam recess 56, the platen 18 returns to its original position by the force of the wave washer 21, and the solenoid 61 is de-energized, so the plunger 62 returns to its original position by the force of the spring 63. The cam follower 58 and the cam recess 56 are disengaged from each other. The platen 18 rotates until the optical sensor 87 detects the hole 84 in FIG. 20, and one end of the printing paper P is above the paper guide 12 and is pressed against the platen 18 by the weight of the flap 16 and stops. .

一連の動作が終了する。 The control section rotates the platen 18 counterclockwise from the state shown in FIG. 20 to eject the printed paper P. In this process, the tension roller 34 rotates together with the platen 18 through the printing paper P without being braked by the one-way clutch 40, so that the printing paper P held between the platen 18 and the flap 16 does not loosen. be discharged. Further, one end of the printing paper P is guided by the flap 16, rides smoothly onto the paper guide 12, and is ejected. When the optical sensor 85 detects the hole 82 in the state shown in FIG. 12, the rotation of the platen 18 is stopped. . At the same time, or by pressing the print end button, the solenoid 31 is energized and attracts the plunger 32, causing the cam 24 to rotate counterclockwise to create a gap between the cam 24 and the platen 18. Release the fixation of paper P. Then, move the printing paper P to the paper guide 12.
When the optical sensors 79 and 78 are pulled out, the output of the optical sensors 79 and 78 disappears in that order, the solenoid 31 is deenergized, the gap between the platen 18 and the cam 24 disappears, and the series of operations ends.

After a certain level of black density has been achieved through color printing, black printing is performed by shifting the distance between the heat-sensitive elements by approximately half a pitch.
This method has the advantage that it is possible to perform color printing without color misregistration, and at the same time, it is possible to effectively express the density by increasing the density of black. As a result, the image quality can be improved without causing color shift, and the contrast of the blacks showing the outlines is improved, which has the advantage of improving the resolution.
